Silver Tubes is the world's renowned industry that is dealing with a greater extent as a producer, supplier, stockiest and exporter of SS 904L Tubes, which is one of the few stainless sheets of steel that at temperatures of up to 35 Degree C/ 95 Degree F provides maximum resistance in dilute sulfuric acid environments within the entire range of concentration, from 0-100percent. 904L Seamless Tubes (UNS NO8904) is a non-stabilized austenitic stainless steel with low carbon content. Stainless Steel 904L Welded Tubes is a low carbon high alloy austenitic stainless steel which is widely used in applications where the corrosion properties of Stainless Steel 316L and Stainless Steel 317L are not adequate. Stainless Steel 904L EFW Tubes are added with copper to improve resistance to strong reducing acids, such as sulphuric acid. 904L ERW Tubes is also resistant to stress corrosion cracking and crevice corrosion. Grade 904L is non-magnetic and offers excellent formability, toughness and weldability.
Stainless Steel 904L EFW Tubes contains high amounts of expensive ingredients, such as molybdenum and nickel. The addition of copper to Type 904L Tubes gives it corrosion resistant properties superior to the conventional chrome nickel stainless steels, particularly sulphuric, phosphoric and acetic acids. Grade 904L Tubes is non-magnetic in all conditions and has excellent formability and weldability. Meanwhile, the austenitic structure also gives 904L Stainless Steel Tubesexcellent toughness, even down to cryogenic temperatures. Alloy 904L Tubes was originally developed to withstand environments containing dilute sulfuric acid.
The standard specifications of this grade tube are ASME SB/ ASTM B 675 / SA977. The dimensions of it range from ASME, ASTM, and API. The sizes of the tube are ranging from 1/8" NB to 30"NB IN. The tubes are in 0.35mm to 6.35mm OD in thickness of 0.1mm to 1.2mm. The schedule is SCH 30, 20, 40, 80, 60, 120, 140, and 120, XS, XXS, and STD. The types of tubes available are ERW, LSAW, welded, fabricated and seamless. The forms of it are square, hydraulic, round, rectangle etc. The length in which it is available is single and double random and cut length. The ends are bevelled, treaded and plain.
The Stainless Steel 904L Tubes is packed carefully using various techniques like wooden boxes, wooden crates, and carton boxes, shrink-wrapped.
